摘要： A non-aqueous electrolyte secondary battery includes an electrode body including a positive electrode and a negative electrode superimposed upon each other with a separator interposed therebetween. The negative electrode is superimposed upon the positive electrode in a state where a negative electrode active material layer, except the part on a proximal end part of a negative electrode tab, is positioned inside an outer edge of a positive electrode active material layer of the positive electrode. A width H1 of the negative electrode active material layer including the part on the proximal end part of the negative electrode tab, width H2 of the negative electrode active material layer or negative electrode current collector at a part other than the negative electrode tab, and width H3 of the positive electrode active material layer are formed to satisfy the relationships of H2

摘要： A nonaqueous electrolyte battery includes a case, an electrode group, positive electrode tabs and negative electrode tabs. The electrode group comprises a positive electrode, a negative electrode and a separator. The positive electrode, the negative electrode and the separator are spirally coiled in a flat form. The positive electrode tabs are electrically connected to at least two positions among tab positions Pn of the positive electrode and projected from one end surface of the electrode group. The negative electrode tabs are electrically connected to at least two positions among tab positions Nn of the negative electrode and projected from the one end surface.
